Definitions

  • the invention relates to a track chain for tracked vehicles, consisting of a series of chain links which are connected to one another by elastic connecting pieces, the connecting pieces engaging with their T-shaped ends in correspondingly T-shaped grooves of the chain links.
  • the invention is based on the object of designing a caterpillar of the type mentioned at the outset in such a way that it does not have the abovementioned disadvantages and permits elastic camber of the caterpillar when it loops around the deflection rollers without flexibility in the longitudinal direction of the chain.
  • the connecting pieces are designed as one-piece metal springs.
  • the T-shaped ends of the connecting pieces lie with their opposing surfaces firmly against the relevant surfaces of the grooves, so that there is no freedom of movement in the longitudinal direction of the chain.
  • the elasticity of the metal springs forming the connecting pieces is large enough to allow the track chain to bend.
  • the outer contour of the connecting pieces between the middle part and the T-shaped ends has a concave transition, so that there is a favorable course of the force lines in the connecting pieces.
  • the width of the grooves is greater than the width of the T-shaped ends of the connecting pieces and a clamping element is arranged between each end of the connecting pieces and the relevant base area of the grooves. This tensioning element ensures that the ends of the connecting pieces rest securely on the relevant surfaces of the grooves, which results in very smooth running and very precise guidance of the chain.
  • the tensioning elements consist of rubber or an elastic plastic; on their side facing the base of the groove, they have a slide bar which facilitates the insertion of the tensioning elements into the grooves; and they're biased.
  • each connecting piece is provided on its top and bottom with a layer of elastic material. This prevents the penetration of abrasive substances.
  • the advantages of the caterpillar track according to the invention over the known caterpillar tracks are that the caterpillar track does not undergo any lengthening which causes the chain to vibrate and that the clear contact of the T-shaped ends of the connecting pieces on the relevant surfaces of the grooves means that there is no movement between the ends of the connecting pieces and the grooves and therefore no wear occurs. Furthermore, the distance between the individual chain links can be selected to be relatively small in the case of the crawler belt according to the invention, which has an advantageous effect on the rolling of the chain on the ground.
  • the track chain shown consists of a sequence of chain links 1 which are connected to one another by elastic connecting pieces 2.
  • the connecting pieces 2, which are designed as one-piece metal springs, have T-shaped ends 3 which engage in correspondingly T-shaped grooves 4 of the chain links 1.
  • the outer contour of the connecting pieces 2 has a concave transition between the central part 5 and the T-shaped ends 3.
  • the width B of the T-shaped part of the grooves 4 is greater than the width b of the T-shaped ends 3 of the connecting pieces 2, so that a space remains between the ends 3 and the base 7 of the grooves 4, in each of which a clamping element 8 is used.
  • the clamping elements 8, which are provided on their side facing the groove 4 with slide strips 9, are under a pretension, i.e. before they are inserted into the groove 4, the width of the clamping elements 8 is greater than the difference between the width B of the grooves 4 and the width b of the T-shaped ends 3 of the connecting pieces 2.
  • a layer 10 of elastic material is provided on the top and bottom of the middle part 5 of each connecting piece 2.
